Finding a good diving mask was a very important issue for me, I've tried several models of different makes some very good and others very poor. When I found this mask Leisurepro struck me, is expensive, but it was a very good price compared to other stores, I bought and I do not regret anything. Worth every dollar spent on it. The Hollis M1 is excellent, the clarity of tempered glass is exceptional, the fit is perfect which does not allow entry of water, has very good viewing angle and is not common that it forms fog, before each dive I put a fog droplets and is sufficient to have a clear and clean glass throughout the dive. A few months ago I had a major emergency in the Pacific product of shock waves or currents of two so strong that at 30 feet depth of water that shot I wanted to tear off the mask twice while I was spinning like a top, it was like being inside of a washing machine. In the midst of this emergency it was very easy to empty the mask of water which entered greatly facilitated me to stay calm and get out of the emergency with my two dive buddies, we can tell. What more can you ask this diving mask ...!

Needs a good cleaning once received or it will fog easily. After scrubbing lens from internal side it fogs no more. The only problem with this mask is its bad strap. It is too thin and too soft. You cannot adjust it tightly, soft small teeth cannot hold grip. Soft thin rubber stretches too well and cannot hold the mask consistently well pressed to a face, it leaks then. Had to buy a generic strap, works like a charm now. Otherwise it is not a bad mask.

I know mask fit is different for each person but this mask is very comfortable, does not for or leak and is my favorite mask. I have about 5 masks in my collection now as I am in the process of becoming a dive master and instructor so I like to have extra gear for students. This is by far my favorite mask. The silicon is soft and molds to the face and in general it's a great mask. I do different types of diving from wreck diving off NC coast to Caribbean diving.

Bought this mask to replace an Atomic mask I lost with luggage along with my primary regulator and my Suunto Cobra 2. I needed a good mask for a Caribbean dive trip and went with the Hollis because of good reviews.

Overall I like the mask very much. It does not leak, which has been a problem with some masks on my face, does not fog, and provides the best field of vision I have experienced.

The one negative is that it seems to be more prone to mask squeeze than any other mask I have used. On 20% of my dives on the trip, I had to partially flood then clear to eliminate squeeze.

This mask is VERY comfortable, But vision is the most important thing. Since I am underwater to SEE things I wanted a mask with the best field of view. Downward visibility of your torso is amazing, and its side vision has to be unparalleled. The only mask that approached this one was the Atomic Aquatics Frameless, but it was too wide for my narrow face. (Even though it is comfortable, the TUSA Vision Pro has a comparatively poor field of view ).
